Fast and Furious gun found at Mexican crime scene

Another weapon from the federal Bureau of Alcohol, Tobacco, Firearms and Explosives agency’s controversial Operation Fast and Furious was recently recovered at a Mexican crime scene, CBS News has learned.

Congressional investigators say the crime scene was likely where a recent shootout took place between reported Sinaloa drug cartel members and the Mexican military, in which Sinaloa beauty queen Maria Susana Flores Gamez and four others were killed.
